[pygtk] Generating theme-compatible colors

I am looking for a way to automatically get a set of related colors that
go well with the current theme. Because multiple sets of colors are
needed, I can't simply use the theme color.
(Explanation: I am writing an application in which colored boxes are
added into a text field, and the colors of each box are picked
automatically depending on the user who added them.)
Has anyone done this before me? My current (braindead) approach looks
palette = [(0.12, 0.29, 0.49),
(1.0, 0.90, 0.34)]
def from_string(string, n_colors = 3):
first = string.__hash__() % (len(palette) - n_colors)
if n_colors == 1:
return [palette[i] for i in range(first, first + n_colors)]
This somewhat works, but the colors often don't go well with each other,
and a white box may be invisible on a theme in which textview widgets
have a white background.
Any idea how to do this properly?
